Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
Assembly Spaces: Formal Definitions and Fast Methods for Approximating Assembly Indices
Gage Siebert, Redwan Chowdhury, Louie Slocombe +1
Assembly theory is an experimental and theoretical framework that introduces a metrological approach to detecting life, with potential applications across diverse substrates. Its t…
Deep-time consistency in proteome elemental composition across cellular and viral life
L. Felipe Benites, Louie Slocombe, Sara I. Walker
Proteins are constructed from a limited alphabet of ~20 amino acids, yet the origins and selection of this specific alphabet are unresolved. One largely overlooked aspect is whethe…
Searching for Life-As-We-Don't-Know-It: Mission-relevant Application of Assembly Theory for Exoplanet Life Detection
Sara Walker, Estelle Janin, Evgenya Shkolnik +2
This white paper introduces a framework for applying Assembly Theory (AT) to planetary atmospheres as a biosignature framework suitable for the Habitable Worlds Observatory (HWO).…
The Emergence of Chirality from Metabolism
John F. Malloy, Camerian Millsaps, Kamesh Narasimhan +4
Molecular chirality is critical to biochemical function, but it is unknown when chiral selectivity first became important in the evolutionary transition from geochemistry to bioche…
